[0013] A cooling garment according to a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the cooling garment is a vest-type cooling vest 1, the garment body 3 of which is made of a synthetic fiber fabric such as nylon or polyester. The back body 5 and the left and right front body parts 7 and 9 are connected via the shoulders and are made of a breathable mesh fabric. The underarm areas between the left front body 7 and the back body 5, and the underarm areas between the right front body 9 and the back body 5 are each connected by a belt 11, and the left front body 7 and the right front body 9 are also connected by a similar belt.

[0014] The bag cloth portion 13a and the bag cloth portion 13b are overlapped from the outer side and sewn together with the back body 5 to form the cooling pocket 15. The bag cloth portion 13b is cut upward in an arc shape to form the flap-like lid portion 15b of the cooling pocket 15, and its base end side is connected to the remaining pocket body 15a. The flap-like lid portion 15b is opened and closed with the pocket body 15a by fasteners 17 provided on each edge. The bag cloth portion 13c is overlapped from the outer surface side and sewn together with the bag cloth portion 13b to form a pump pocket 19, which is opened and closed by a fastener 21 provided by cutting open the bag cloth portion 13c. A separate bag cloth portion 13d is sewn to the inner surface of the flap-shaped lid portion 15b to form an inner pocket 23 that opens upward.

[0015] Also, insertion-type guide parts 25, 25, ... are attached to the inner side of the garment body 3. The inner side and the cooling pocket 15 communicate via an insertion hole 27, and the pump pocket 19 communicates via insertion holes 29, 31. Also, the cooling pocket 15 has not only the above-mentioned flap-shaped lid part 15b, but also an opening at the top near the shoulder part of the garment body 3 to form a cable outlet.

[0016] The garment body 3 is constructed as described above, and incorporates a cooling fluid circulating mechanism that utilizes the tube 33 as a cooling portion. The tube 33 is made of plastic and is flexible, and is inserted in sequence through the insertion-type guide portions 25, 25, ... and wound in a meandering manner along the inner surface, with the inner surface being covered entirely by the tube 33, which is exposed. When the garment body 3 is worn, this meandering portion comes into contact with the wearer's outerwear.

[0017] Both ends of the tube 33 are passed through the insertion holes 27 and enter the cooling pocket 15. The cooling pocket 15 contains a vertically long rectangular flat bag 35 made of a flexible plastic material and open at the top, and the flat bag 35 constitutes the storage section. The flat bag body 35 is housed in a state in which one bag surface portion 35a is overlapped on the pocket main body 15a side.

[0018] As shown in FIG. 6, the bag mouth 35c of the flat bag body 35 is closed with a plastic closing member 37. A rod 37a is fixed parallel to the opening edge of the other bag surface portion 35b, and a piece with a hole 37b is connected to the rod 37a. On the other hand, a long and thin clip 37c is provided as a separate body. A groove 37d is formed in this clip 37c into which the rod 37a is fitted, and a piece with a hole 37e is also connected to the clip 37c. The length of the rod 37a is slightly larger than the width of the bag surfaces 35a and 35b, and both ends of the rod 37a protrude slightly outward in the left-right direction beyond the bag surfaces 35a and 35b.

[0019] When the rod 37a is passed through the groove 37d of the clip 37c, the groove 37d expands elastically, so that the rod 37a and the clip 37c come into elastic contact with each other. Therefore, when the bag mouth 35c is closed and the rod 37a is folded back in the direction of wrapping, and the bag surface parts 35a and 35b wrapping the rod 37a are passed through the groove 37d of the clip 37c, the bag surface parts 35a and 35b are pinched and tightly attached at the folded back parts, so that the bag mouth 35c is closed and the flat bag body 35 is in a closed state. The length dimension of the clip 37c is sized so that the groove 37d completely wraps the rod 37a. Therefore, the bag mouth 35c is completely closed. The flat bag body 35 is provided with a zipper 38, and when the flat bag body 35 is temporarily closed with the zipper 38, the bag surface portions 35a, 35b on the bag mouth 35c side are overlapped in advance, so that the opening edge constituting the bag mouth 35c is neatly aligned.

[0020] 2, one end of the tube 33 inserted into the cooling pocket 15 is connected at its upper part to the flat bag body 35. The other end of the tube 33 is further passed through the insertion hole 29 and drawn out to the pump pocket 19. Then, after the pump 39 is attached, the tube 33 is returned through the insertion hole 29 into the cooling pocket 15 and connected at its lower part to the flat bag body 35. A cable 39a of the pump 39 is passed through the insertion hole 31, enters the inside of the cooling pocket 15, and is pulled out from the cable outlet. The pulled cable 39a is detachably connected to a portable controller. The controller is stored in a pocket on the left front body. The pump 39 is started / stopped by manually operating an operation part on the controller.

[0021] The cold insulator is accommodated in the flat bag 35 so as to be freely inserted and removed. As shown in Fig. 3 and Fig. 4, this cold insulator is composed of a container 43 in which a freezable liquid (L) is enclosed, and its external shape is a flat, plate-like body similar to the flat bag 35. In this embodiment, the liquid (L) is water, which may be potable or non-potable. The container 43 is made of rigid plastic (in this embodiment, polyethylene (PE)), molded into a flat rectangular box shape with thin walls, and is stored in an upright position with a pair of large-area main surface portions 43a, 43a facing horizontally. The space between the main surface portions 43a is a side surface portion, and in the upright position, the side surface portion is made up of a lower surface portion 43b and side portions 43c, 43c on the left and right sides, forming an upper portion.

[0022] The upper part of the container 43 is raised upward from the center on both the left and right sides in a rectangular box shape. The raised parts simply extend flush upward and do not protrude in the front-to-back direction or outward to the left or right. The raised parts form an empty chamber 45. The opposing surfaces 45a, 45a of the empty chamber 45 are inclined surfaces that are inclined upward in directions away from each other. Since the empty chambers 45 are on both the left and right sides, the central upper surface 43d is positioned one step lower than the left and right sides. The upper surface 43d has a round opening on the center side, and a nozzle 47 rises along the edge of the opening. A thread 47a is formed on the outer periphery of the nozzle 47. The height of the nozzle portion 47 is approximately the same as that of the empty chamber portion 45 .

[0023] The container 43 is closed with a double lid. The inner lid portion 49 has a cylindrical body 49a, and the axial upper side of the inner lid portion 49 is closed with a disk 49b, which protrudes radially outward beyond the cylindrical body 49a. A cover 51 is also used as an outer lid. A thread 51a is formed on the inner peripheral surface of the side surface of the cover 51. When the cylinder 49a of the inner lid part 49 is pressed into the mouth part 47 of the container 43, the disk 49b rests on and presses against the upper edge of the mouth part 47. Furthermore, when the side part of the cover lid part 51 is fitted onto the side part of the mouth part 47 and screwed forward, the top surface of the cover lid part 51 rests on and presses against the disk 49b. The opposing surfaces 45a, 45a of the empty chambers 45, 45 are inclined surfaces, and the gap between the nozzle portion 47 and the inner lid portion 49 and the covering lid portion 51 is larger at the upper part, making it easier to bring the inner lid portion 49 and the covering lid portion 51 closer to the nozzle portion 47. By closing the lid as described above, the container 43 is sealed and the liquid (L) does not leak.

[0024] Inside the container 43, a reinforcing part 53 is provided that is a rectangular flat plate extending straight in a direction perpendicular to the main surface parts 43a and 43a. The plate surface of the reinforcing part 53 faces the left-right direction. A pair of opposing sides of the reinforcing part 53 are connected to the main surface parts 43a and 43a, respectively, and are integrated and partitioned in the left-right direction, but are open above the upper edge and below the lower edge, and inside the container 43, the upper and lower sides are connected in the left-right direction.

[0025] The reinforcing portion 53 is formed by connecting and integrating vertical ribs forming grooves recessed inwardly from the opposing main surface portions 43a, 43a at the center of the container 43. The outer surface corresponding to the inner side surface 53a of the groove-shaped portion forms the plate surface of the reinforcing portion 53, and the inner bottom surface 53b side of the groove-shaped portion extending from one main surface portion 43a is connected to the inner bottom surface 53b side of the groove-shaped portion extending from the other main surface portion 43a. The reinforcing portions 53, 53 are provided as a pair in the left-right direction and are located below the empty chamber portions 45, 45, respectively. Further, a shallowly recessed groove 55 is formed inwardly at the center in the left-right direction of the main surface portion 43a. The groove portion 55 extends in the up-down direction and has a vertically long rectangular shape.

[0026] When liquid (L) is put into container 43 with the lid closed, the liquid (L) freezes and expands, and at that time, the large-area main surface portion 43a is likely to warp and bulge outward, but the presence of reinforcing portions 53, 53 makes it difficult to warp, and bulging of main surface portion 45a is suppressed. In addition, recessed rib portion 55 also contributes to suppressing warping of main surface portion 43a. The amount of expansion due to freezing is guided to the empty chamber 45. When liquid (L) is put into the container 43, even if the maximum amount is put in, the empty chamber 45 becomes hollow and air (A) is in the empty chamber. Since air (A) is compressible, the amount of expansion caused by putting liquid (L) in and freezing it can enter. Therefore, even if liquid (L) is put into the container 43 and frozen to cause freezing and expansion, the container 43 does not deform and remains flat. Therefore, the back body 5 side of the garment body 3 does not expand from the time when it is first worn. Figure 4 shows the state before the liquid (L) freezes, and Figure 5 shows the state after the liquid (L) has frozen. In Figure 5, the empty chamber 45 is filled with the amount of expansion, and the air (A) is compressed and its volume is reduced.

[0027] When the cooling vest 1 is worn, the liquid (L) sealed in the container 43 is placed in a frozen state in the flat bag body 35 in an upright position as shown in Fig. 6. Water (W) as a cooling fluid is also placed in the flat bag body 35. Then, after first temporarily closing it with the zipper 38 as shown in Fig. 7, the flat bag body 35 is folded so that the rod 37a is hidden as shown in Fig. 8, and then the bag surface parts 35a and 35b enclosing the rod 37a are passed through the groove 37d of the clip 37c together with the bag surface parts 35a and 35b, and the bag opening 35c is closed as shown in Fig. 9.

[0028] By passing a loop made of hook-and-loop tape on the upper side of the cooling pocket 15 through a hole in a perforated piece 37e connected to the clip 37c that closes the flat bag body 35, the flat bag body 35 is stably provided within the cooling pocket 15, as shown in Figure 1. When the pump 39 is operated, the water (W) flowing into the flat bag body 35 from one end side of the tube 33 hits the container 43 in which the liquid (L) is sealed in a frozen state, is cooled, and then is returned to the other end side of the tube 33 to form a cooling fluid circulation path. Therefore, when the cooling vest 1 is worn, the body is cooled by the water (W) circulating inside the tubes 33.

[0029] A feature of this cooling vest 1 is that even when the liquid (L) freezes and expands, no curved bulges are formed on the outer surface of the back body 5, so immediately after putting it on, it looks like normal clothing and there is no discomfort even when the back is pressed against a wall or the back of a chair. Also, as shown in Figure 10, a harness-type safety belt (H) for working at heights can be worn stably.

[0030] Furthermore, in the pocket body 15a of the cooling pocket 15, a gap is formed around the flat bag body 35 housing the container 43, but this gap can be utilized. The neck cooler 57 shown in Fig. 11 is composed of a shape retaining part 59 formed by bending a strip-shaped material having bending elasticity into a C-shape, and a strip-shaped cooling body 61 that is detachably attached to and aligned with the inner surface of the bent part of the shape retaining part 59. The cooling body 61 is formed by overlapping two strip-shaped plastic films, sealing them together, and one of the films is uneven, and the convex part is raised into a square box shape to form a three-dimensional sealed space. A phase change material is enclosed in this sealed space. A plurality of these raised parts 61a are provided in the longitudinal direction of the strip-shaped part with gaps 61b between them.

[0031] The phase change material is a so-called PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase, and contains, for example, paraffin or aliphatic hydrocarbons (or fatty saturated hydrocarbons). It is used as a cooling medium to cool the neck by absorbing heat from the neck as latent heat of fusion. The solidification temperature of the phase change material is adjusted to about 26°C so that it quickly returns from a molten state to a solidified state, for example in about 10 minutes, when placed in a cooler box or cooling bag.

[0032] Since the cooling body 61 can be folded at the gap 61b, it can be folded compactly after being separated from the shape retaining part 59. Therefore, if it is folded and stored in the gap around the flat bag body 35 as shown in Fig. 12, it will be cooled by contacting the flat bag body 35 side, and the cooling body 61 that has warmed and melted will be solidified again. The cooling body 61 may also be placed in the inner pocket 23. In this way, if multiple cooling bodies 61 are stored, the cooling bodies 61 attached to the shape retaining part 59 can be replaced one after another. It is also possible to put a cooling material in the inner pocket 23. By using this cooling material, it is possible to help cool the cooling body 61 and to slow down the progress of melting of the liquid (L) sealed in the container 43 from a frozen state.

[0033] A cooling vest 101 according to a second embodiment of the present invention will be described with reference to FIGS. The cooling vest 101 includes a clothing body 3, a cooling pocket 15, and a pump pocket 19 similar to the cooling vest 1 according to the first embodiment. However, the flow path is formed not by a tube 33, but by two overlapping synthetic resin sheets 103, 103. The two synthetic resin sheets 103, 103 are joined by linear heat sealing. Two sealing lines 105, 105 extend almost parallel to each other, and a long and narrow space is formed between the two sealing lines 105, 105. This space serves as a flow path 107. This flow path 107 extends in a meandering, one-stroke pattern.

[0034] The two overlapped synthetic resin sheets 103, 103 form a cooling lining 109, which is overlapped on the inner side of the garment body 3 as the outer fabric and attached with snap buttons 111. A tube connection part is integrally formed on each of both ends 107a, 107a of the flow path 107 on the side facing the outer fabric. One end of a tube is connected to one of the tube connection parts, and the other end of this tube passes through the insertion hole 113 and enters the cooling pocket 15. The same is true for the tube connected to the other tube connection part. In this way, these tubes are connected to the flat bag body 35 in the same way as the tube 33 used in the cooling vest 1.

[0035] Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and the invention also includes design changes within the scope of the present invention without departing from the gist of the present invention. For example, the way the tube 33 is laid and the density thereof, and the way the flow passage 107 extends in a single stroke may be optimally adopted depending on the size of the body of the garment main body 3, etc. Also, the closing means is not limited to the closure 37 as long as it can achieve the expected closing function.
